Review. A highway curve forms a section of a circle. A car goes around the curve as shown in the helicopter view of Figure P1.48. Its dashboard compass shows that the car is initially heading due east. After it travels d = 840 m. it is heading θ = 3.5.0 south of east. Kind the radius of curvature of its path. Suggestion: You may find it useful to learn a geometric theorem staled in Appendix B.3.

You walk 20 meters at an angle of 25 degrees north of the +x axis. After that, you turn, then walk 20 metors at an angle 45 degrees north of the +x axis. Finally, you turn and walk 10 meters at an angle 15 degrees south of the +x axis. Your friend, still at the origin, walks in a straight line to you in the fastest route. What angle do thoy take, and how many moters do they go?arrow_forwardone day you go hiking at a nearby nature preserve. at first, you follow the straight, clearly marked trails. from your starting point, you travel 2.00 miles down the 1st trail. then you turn to your left by 30.0 degrees to follow a 2nd trail for 1.40 miles. next, you turn to your right by 160 degrees and follow a third trail for 1.90 miles. at this point you are getting very tired and would like to go back. you would like to take a shortcut directly through the woods. how far to your right should you turn, and how far do you have to walk, to go directly back to the darting point. what degree turn to the right must "I" take, and how many miles must I walk back? I know the distance is 2.104 miles, but I cannot figure out the degree angle.arrow_forward
